BECEPTACLE FOR CONTAINING FOODS AND THE LIKE.

Specification of Letters Patent.

Patented July 24, 1917.

Application fiIed March 29, 1916. Serial No. 87,557.

To all wkomz't may concern:

Be it known that I, THOMAS LEO MYERS- coocn, a British subject, residing at 7 4 Brompton road, Rusholme, in the. county of Lancaster, England, have invented certain new and useful Improvements in Receptacles for Containing Foods and the like, of which the following is a specification.

This invention relates to receptacles for containing food and the like and refers more particularly to parchment pots, wood pulp vessels and all vessels made from paper, cardboard or woodpulp board-or the like for containing cream, preserves or other articles of food.

It has been customary, up to the present time, to make these vessels from paper, cardboard or wood pulp of suitable thickness, formed into a tapering or other tube, the lower ends of the tube being turned up so as to form-a grooved rim, into which a corresponding flanged portion of the bottom of the vessel is fitted when the vessel is made up.

With this construction it is found in practice that in spite of waxing or otherwise treating the parchment pot, the vessel, after being for some time in use has a .tendency to leak, that it is not suitable for the reception of hot preserves and other liquids, which it is intended to Store in the vessel for a' prolonged period, that 'no means are provided for preventing the'rapidradiation of heat out of or into the vessel, and that it can be easily upset.

My present invention relates to an imroved construction of receptacles of the be orementioned description in whichmeans are provided for rendering the bottom of the vessel liquid tight and where desired for preventing the rapid-heating or cooling of the contents of the vessel, while rendering the vessel more stable.

In carrying out my invention, I construct a wood pulp receptacle of the ordinary description, by means of any ordinary machine, providing the same in the usual manner with an upturned grooved rim at the bottom and I provide also in the'customary manner a bottom piece of. wood pulp or the like or some other material, such as wood, tin or aluminium, provided with a downwardly turned flange adapted to fit into the aforesaid grooved rim at the bottom of the outer shell.

After the bottom portion has been placed in position in the ordinary manner, I provide a filling of plaster or cement or other suitable plastic material or mixture of materials, such for instance as plaster of Paris, which filling is introduced in a plastic condition into the space or depression at the bottom of the vessel. This filling after being lntroduced in a plastic condition is allowed to harden and when hard forms a seal which effectually prevents the leakage of liquids contained in the vessel, which renders the vessel suitable for the reception of preserves in the hot condition, and which prevents the rapid communication of heat to or radiationof heat from the contents of the vessel.

In order that my said invention may be better understood I will now proceed to describe the same with reference to the drawing accompanying this'specification, which shows a vertical section of a parchment or wood pulp pot with my invention applied thereto. 7 v

a is the tapering side of the pot, which has a lower turned up edge I). c is the bottom of the pot which is provided with a downturned flange d which is adapted to fit into the portion 1;.

After the bottom has been placed in position it is suitably supported, if necessary, and the vessel is inverted and a filling e of suitable plaster or cement, such for instance as plaster .of Paris is inserted into the depression or recess at the lower portion of the vessel, in a plastic condition.

When the composition sets hard it is found that the vessel is rendered perfectly liquid tight, that it will not leak even when hot preserves are poured into the Same, while the filling acts as an insulator preventing the rapid radiation of heat out of or into the vessel.

I have found in practice that plaster of Paris is a particularly suitable composition for filling in the bottom or depressed portion of the wood pulp vessel, but I- wish it to be understood that I may use other compositions, as any cement (glue, sealing wax or the like) or plaster which is adapted to seal the bottom of the vessel and to prevent the rapid radiation of heat out of or into the vessel will suit my purpose. For instance I may use a composition of plaster of Paris mixed with fibrous asbestos, oXid of zinc or other analogous material. A mixture of plaster of Paris and glue answers well.

Any suitable binding material such for instance as hair may be introduced into the cement in order to render the composition firmer and more durablewhen set. The bottom of the vessel may be constructed in other ways, provided there is a recess or depression.

The device or improvement also acts as a stabilizer.

What I claim as my invention and desire to secure by Letters Patent of the United States of America is 1. A vessel of the character described, comprising in combination with the lower turned up edge of the vessel, a flanged bottom fitting between the Wall of the vessel and the lower turned up edge of the same and a filler-in the depressed portion at the bottom adapted to prevent the egress of heat from and the absorption of heat by the vessel, substantially as' described and for the purpose set forth.

2. A vessel of the character described, comprising in combination with the lower turned up edge of the vessel, a flanged bot-- tom fitting between the-Wall of the vessel and the lower turned up edge of the same and a cement filler in the depressed portion at the bottom adapted to present a'liquid seal, heat insulator and stabilizing device, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses;

THOMAS LEO MYERSCOUGH.
